That's pretty cool, I'll read through that tonight while on the plane.

They did a really nice job with this redesign.
Putting the diesel oxidation catalyst right on the tail of the turbo really helps meet emissions sooner on a cold engine which gives them more fuel to play with later when it's hot.
Also they have been using a ninth injector in the exhaust to feed fuel during regeneration which is a superior, engine-turbo saving approach.
They changed high pressure fuel pumps this year to a Denso unit that is superior to the Bosch unit.

I prefer the method Ford has used with reverse flow heads that send exhaust gas right into the turbo without all the extra piping.
I wish my Ford had the Denso pump and ninth injector.
